According to 'The Hollywood Reporter', Universal Pictures is in negotiations with Michael De Luca Productions and Immersive Pictures over the rights to the film.

Ono has been named as a producer, alongside McCarten, De Luca and Josh Bratman.

“The film project came about after Bratman lobbied Ono to bring the story of her relationship to the screen with De Luca. McCarten worked with all three to write the story on spec.”

The iconic couple are said to have met in 1966 at a London art gallery, where Lennon became fascinated with one of the artworks Ono had on display: a ladder that led to a canvas suspended from the ceiling, with a tiny world printed on it and a magnifying glass to allow it to be read.

"You're on this ladder – you feel like a fool, you could fall any minute – and you look through it and it just says 'yes,'" Lennon said of the work in 1980, "Well, all the so-called avant-garde art at the time, and everything that was supposedly interesting, was all negative; this smash-the-piano-with-a-hammer, break-the-sculpture, boring, negative crap. It was all anti-, anti-, anti-. Anti-art, anti-establishment. And just that 'yes' made me stay in a gallery full of apples and nails, instead of just walking out saying, 'I'm not gonna buy any of this crap.'"

The couple were married in March of 1969, and staged a famous bed-in during their honeymoon. The pair remainded together until Lennon died in 1980, despite a reportedly tumultuous and unusual relationship.
